I got 2 Screen resolution (1366x768) and (1920x1080) i am using the first one like 80% cuz the other one is my Tv .anyway I have 9500 GT and I want to buy a new one My budget is 140$. I never used radeon but a lot of people said nvidia is better than Radeon .my options are GTS 450 , GTX 460 ( if I find the 1GB version I will buy it ) and GTX 550 Ti. Which one of them will run today games on both of my screen resolution in high or med? If there is something better i can get it with my budget plz tell me ?
Raise your budget by $20 and get a 7850 or a 650 ti. Both will outperform all of those cards you mentioned by a wide margin. Nvidia was better than ati for a while mostly due to driver issues, but amd bought ati, and their drivers have gotten a lot better recently.
